What term best describes cell A compared to Cell B
- A.
Hydrophylic
- B.
Hypertonic
- C.
Isotonic
- D.
Hypotonic
Correct Answer
B. HypertonicExplanation
Cell A is described as hypertonic compared to Cell B. This means that the concentration of solutes in Cell A is higher than in Cell B. In a hypertonic solution, water tends to move out of the cell, causing it to shrink or shrivel.Rate this question:

The reproductive cycle in a human female is not functioning properly. An imbalance of hormones is diagnosed as the cause. Which of the following hormones are directly involved in the human female reproductive system and could cause this problem.
- A.
Testosterone, HCG, LH
- B.
Progesterone, HCG, testosterone
- C.
FSH, estrogen, insulin
- D.
Estrogen, progesterone, FSH, LH
Correct Answer
D. Estrogen, progesterone, FSH, LHExplanation
Estrogen, progesterone, FSH, and LH are directly involved in the human female reproductive system. Estrogen is responsible for the development of secondary sexual characteristics and the growth of the uterine lining. Progesterone helps in preparing the uterus for pregnancy and maintaining the pregnancy. FSH (follicle-stimulating hormone) is involved in the development of ovarian follicles, which contain the eggs. LH (luteinizing hormone) triggers ovulation and stimulates the production of progesterone. An imbalance in these hormones can disrupt the reproductive cycle and cause problems in the female reproductive system.Rate this question:

The relative concentration of solute inside and outside of a cell can cause water molecules to move across the membrane. Which phrase would be an alternate title to the diagram?
- A.
Diffusion
- B.
Osmosis
- C.
Active transport
- D.
Endocytosis
Correct Answer
B. OsmosisExplanation
The diagram is likely depicting the process of osmosis. Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement of water is driven by the difference in solute concentration between the inside and outside of the cell. Therefore, "Osmosis" would be an appropriate alternate title for the diagram.Rate this question:

Which statement best explains why some cells in the reproductive system only respond to certain hormones?
- A.
These cells have different DNA than the cells in other body systems.
- B.
These cells have specific types of receptors on their membranes.
- C.
Reproductive system cells could be harmed if they made contact with hormones from other different body systems.
- D.
Cells associated with the female reproductive system only respond to the hormone testosterone.
Correct Answer
B. These cells have specific types of receptors on their membranes.Explanation
The statement that best explains why some cells in the reproductive system only respond to certain hormones is that these cells have specific types of receptors on their membranes. Receptors on cell membranes are responsible for recognizing and binding to specific hormones, allowing the cells to respond to them. Different cells have different types of receptors, which determine which hormones they can respond to. This is why some cells in the reproductive system only respond to certain hormones, as they have specific receptors that are designed to recognize and interact with those particular hormones.Rate this question:

When organisms break the bonds of organic compounds, the organisms can
- A.
Use the smaller molecules to plug the gaps in the cell membrane to slow diffusion
- B.
Use the energy obtained to digest molecules produced by respiration that uses oxygen
- C.
Obtain energy or reassemble the resulting materials to form different compounds
- D.
Excrete smaller amounts of solid waste materials during vigorous exercise
Correct Answer
C. Obtain energy or reassemble the resulting materials to form different compoundsExplanation
When organisms break the bonds of organic compounds, they can obtain energy or reassemble the resulting materials to form different compounds. This is because breaking the bonds releases stored energy, which can be used by the organism for various metabolic processes. Additionally, the resulting smaller molecules can be used as building blocks to create new compounds that are needed for growth, repair, or other biological functions. This process allows organisms to efficiently utilize the resources available to them and maintain their cellular functions.Rate this question:

A laboratory setup using an artificial cell made from dialysis tubing is shown in the diagram below. Identify the process that would most likely be responsible for the movement of glucose from inside the artificial cell to the solution outside of the cell.
- A.
Diffusion
- B.
Osmosis
- C.
Active Transport
- D.
Endocytosis
Correct Answer
A. DiffusionExplanation
The movement of glucose from inside the artificial cell to the solution outside of the cell is most likely due to diffusion. Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration. In this case, the concentration of glucose is higher inside the cell, so it naturally moves to the area of lower concentration outside the cell.Rate this question:

This laboratory setup would most likely be used to demonstrate
- A.
Carbohydrate synthesis
- B.
Active transport
- C.
Diffusion
- D.
Dehydration
Correct Answer
C. DiffusionExplanation
This laboratory setup would most likely be used to demonstrate diffusion. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In this setup, it is likely that there are two compartments separated by a membrane, and a substance is added to one compartment. Over time, the substance will passively move through the membrane and distribute evenly in both compartments, demonstrating the concept of diffusion.Rate this question:

Which situation indicates that a disruption of homeostasis has taken place?
- A.
The presence of hormones that keep the blood sugar level steady
- B.
The maintenance of a constant body temperature
- C.
Cell division that is involved in normal growth
- D.
A rapid rise in the number of red blood cells
Correct Answer
D. A rapid rise in the number of red blood cellsExplanation
A rapid rise in the number of red blood cells indicates a disruption of homeostasis because it suggests an abnormal increase in the production of red blood cells. Homeostasis involves maintaining a stable internal environment, and an excessive increase in red blood cells can disrupt the balance of blood components. This could be caused by a medical condition such as polycythemia vera, which leads to an overproduction of red blood cells and can disrupt the normal functioning of the body.Rate this question:

Some people with spinal cord injuries do not sweat below the area of the injury. Without the ability to sweat, the human body temperature begins to rise. Which statement would best describe this situation?
- A.
Feedback mechanisms regulate blood sugar levels.
- B.
Gene mutations are increased.
- C.
Energy from ATP is not available.
- D.
Dynamic equilibrium is disrupted.
Correct Answer
D. Dynamic equilibrium is disrupted.Explanation
The inability to sweat below the area of a spinal cord injury disrupts the dynamic equilibrium of the body. Sweating is an important mechanism for regulating body temperature. When the body temperature rises, sweating helps to cool down the body by evaporating the sweat from the skin. Without the ability to sweat, the body cannot effectively regulate its temperature, leading to an imbalance in the dynamic equilibrium.Rate this question:

The diagram below shows molecules represented by X both outside and inside of a cell. A process that would result in the movement of these molecules out of the cell requires the use of
- A.
DNA
- B.
ATP
- C.
Antigens
- D.
Antibodies
Correct Answer
B. ATPExplanation
ATP (adenosine triphosphate) is a molecule that provides energy for cellular processes. In order for molecules to move out of the cell, energy is needed to overcome the concentration gradient. ATP can be used as an energy source to power active transport processes, such as pumping molecules against their concentration gradient through the cell membrane. Therefore, the use of ATP is required for the movement of molecules out of the cell.Rate this question:
